Description
The diffuse stellar component of galaxy clusters known as intracluster light (ICL) has been proposed as an observable tracer of the cluster’s dark matter (DM) halo. Investigating the energetics of the intracluster stars is essential for understanding how they are linked to the underlying DM distribution and, consequently, assessing the reliability of the ICL as a DM tracer. In this talk, I will outline how the orbital properties of the intracluster stars differ from both the DM and galaxy population, and propose a possible mechanism to explain these differences.
